CABLE-BRACKET.

To all whom it may concern y Be it known that I, HENRY BRACHTL, a. .l 'citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a' certain new and useful Improvement in Cable-Brackets, of which the following is a full, clear, concise, and exact descriptlon, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to cable brackets or supports and lhas for its object the provision of a bracket of this nature which is easily and readily attachable to suitable means l5 of support suchas a manhole wall or the wall of a house, and which is provided with suitably formed means adapted to receive a saddle or other device for supporting a cable. One of the objects of my invention is the rovision of a device of the nature described 1n which the back portion and the arm portion are provided with means whereby they may be readily mounted together or sepa- I5 rated, as may be required.

A further object of my invention is the provision of an arm portion for the bracket which'is of such a nature that the arm portion clears a cable mmmted below the arm l0 portion upon a second arm portion.

A further object of the invention is the construction of an arm portion in a very `simple and highly eilicacious manner.

In one form of the invention, I ind it 88 particularly desirable to construct the arm portion of bent piping so formed at its extremities to coperate with 'the back portion and inter-lock therewith. structing the arm portion of the material 40- suggested it is very substantial and unbreakab e.

I will describe the preferred form which ny inventipllli may take more ilrgetail blyl'l reernn' g to e accompanying wing us- 46 trating Such embodiment, in which- Figure 1 is a side view partly in section vof my improved device;

Fig. 2 la a `front view Fig. 3 is a sectional view on hne 3 3 of 50F'.1,and

' .4isasect1onal view on 11ne4-4' of Fig. 1.

My improved device conslsts of the back portion 10 which through' the agency of bolts 11, 11 may be suitably mounted in place upon apwall 12. The back portion, as

' portion 23 forming Specication 0f Letters Patent Patented Mar. 30, 1920.

`Application filed June 6, 1918f Serial No. 238,496.

more clearly apparent from Figs. 3 and 4, is constructed of one of the commercial shapes known as channels and is provided with a plurality of holes 13 therethrough. 60 The general outline of these holes is circular except thatradially arranged notches 14, 14 project upwardly and downwardly therefrom. These holesy 13 are of suchv a nature that they will accommodate both the l upper and lower legs of the arm portion 15 of my improved bracket. This arm porf tion, as stated, has two legs, respectively, the legs 16 and 17. The leg 16 is substantially straight and is adapted to support the saddle or saddles 18, these saddles having projecting downwardly therefrom clamping elements 19, 19, preferably spring-like in character, which encircle the leg 16 and hold the 'saddles 18 in place. These saddles 18 vthen 75 support the cable 20, indicated in dotted lines in Fig. 1. The arm portion 15 is'made 4 of pipe bent into the required form, as shown. The free extremity of the leg 16 is formed by having the extremity 21 pressed substantially into flat rectangular form, thereby providing shoulders 22, 22, which project outwardly from the leg portion 16, the immediately adjacent part of the leg 16 being held by a mandrel during theprocm of forming so that the part of the leg immediately adjacent the rectangular extremity 21 retains its substantially rounded characteristics so as to it within the hole 13.- The rectangular .extremity 21 is of such a 90 size that it may be introduced through the radial extensions 14, 14 when the leg .por-

tion 16 is swung ninety degrees from the position it occupies in Fig. 1. If the leg 16 is then returned to the position it occupies 95 in Fig. 1, the shoulders 22, 22 abut agalnst the back portion or channel 410, thus to prevent removal of the leg 16. T he extremlg of the leg 17 remains substantially round but near the extremityI provide an up-set an annular ri of a size larger than the hole 13. The ridge 23 coperates to limit the inward movement of the extremity of the leg 17, as more clearly aprent from Figs. 1 and 4.

order to mount the bracket in position therefore all that isnecessary is to swing it ninety degrees from its vertical`position, whereupon the rectangular flattened portion 21 may be inserted through the hole'13 with its radial extensions 14; thereupon the arm portion 15 is swlmg into its vertical posiinserted into one of the holes 13 provided provided in said back portion,

in the back portion 10, the annular enlargement- 23 limiting the inward movement of this leg. The leg shown in Fig. 1, so that it may clear a cable mounted upon the arm portion directly beneath the arm port-ion 15.

In Fig. 1, I likewise show an arm portion 15 having legs 17a and 16a. The extremities of the legs 162L and 17a are constructed exactly the same as the extremities of the legs 16 and 17, the arm portion 15a however being of a smaller type than the arm portion 15, being constructed simply for the supportof one cable instead of two.

FromV what has been thus described the nature of my invention will be readily clear to those skilled in the art.

Having thus described one form which in v invention may take, what I claim as new and desire to secure by Letters Patent is:

1. A cable bracket having a back portion and an arm portion, said arm portion consistingof a pipe a saddle, ine \to secure the saddle to said arm portion, openings of special form provided in said back portion, one ofthe legs of the said arm portion having a widened extremity adapted to interlock with said openings and prevent removal of said leg portion when inserted through one of said openings and rotated into proper position, and an upset portion ormingan annular ridge on the other leg portion to limit the penetration of said leg portion through its coperating opening in the back portion.

2. A cable bracket having a back portion and an arm portion, said arm portion consisting of a member substantially V-shaped,

cable holding means secured to one leg of openings of special form the arm Ifortion,

one of the portion 17 is bent, as`

bent substantially V-shaped,

legs of the said arm portion having a.

said holes and prevent removal of said leg portion when inserted through said hole and rotated into proper position, and means on I y the other leg portion to limit the penetra.- tion of said leg portion through its coperating hole in the back portion, the lower one ofthe legs of said. arm portion being bent inwardly intermediate its length.

3. A cable bracket having a back portion A and an arm portion, said arm portion 'consisting of a pipe bent substantially V-shaped, openings provided' in""sai'tl back portion, formed extremities provided upon the free extremities of the legs of said arm portion to interlock with the openings in said back portion, the lower one of the legs of said arm portion being bent inwardly intermediate its length, and a saddle having means i for attachment to the upper leg of said arm portion.

4. A cable bracket having a back portion and an arm portion, said arm portion consisting of a pipe bent substantially V-shaped, openings of special formk provided in said back portion, one of the legs of said arm portion having a widened extremity adapted to interlock with said holes andprevent removal of said leg portion Awhen inserted through said hole and rotated into proper position, means on the other leg portion to limit the penetration of said leg portionthrough its coperating hole in the' back portion, the lower one of the legs of said arm portion being bent inwardly intermediate its length, anda saddle having means for attachment to the upper leg of said arm portion. g e

In witness whereof, I hereunto subscribe my name this 15th day of hlay, A. D. 1918.
